eA EsBUnG, ILLINOIS, ASSIGNOR TO WILIQIAM E. HAMER- TSTROM, 0F GALESIBURG, ILLINOIS.

HOG-OILER.

To all whomz't may: concern: y

' Be itknown that I, GEORGE VVFERIOSON, aciti-zen of the United States, and a resident of Galesburg', in the county of Knox and State of Illinois, have invented a new and useful Hog Oiler, of'which the following is a specification. lI 1 My invention relates to devices for supplying oil or other liquid to a plate adapted for actuation by an animal rubbing thereagainst, whereby theiliquid will be self-applied to his body, and it consists, substantially, in the improvements hereinafter described. I I I The principal end and object'of the invention isto generally simplify and improve the construction, to increase the utility and efficiency of the device," and todecreasethe expense attendant upon both its inariufacture and use. I I More specifically stated, it is an objectto dispense with the usual centrally arranged leg and with several of the rubbing plates ordinarily employed- In this connection it is an object to so construct the device that it may be secured to a shed, barn, stable, fence, fence-post, tree, or any other suitable object. I I I v To this general class or type of hog-oilers the chief objection has been that when an animal leaned against the vertical rubbingplate, whereby the oil-discliargingmeans wasoperated, the oil would continue-to flow as long asthe pressure was maintained, the majorIportion of the oil being wasted. To provide a device of this character which will permit the dischargeof a measured quantity of oil at each-reciprocation of the plunger or valve-stem, but in which provision is made for cutting off the'discharge of oil While the animal is merely leaning against the rubbing-plate, constitutes one of the most important Ob ects of the invention.

It is an object to dispense with the usual tank. In order to accomplish this object I provide a support for the can in which the oil isshipped tothe-user, and employ said can as the tank. It is notto be understood from the foregoing, however, that a tank of the usual character can not besuccessfully embodied in my improvements. I I

i A further object is to provide a suitable reservoir into which the can discharges oil and from which reservoir the oil passes. to thedischarge means. I I

Specification of Letters Patent. I Patented Sept, 4 1917. Application filed July 29, 1915; Serial No. 42,589.

It is another object to provide a novel bearing for the rubbing-plate;

A special object is to provide a novel valve or cut-off. I 1

An additional object isto provide a novelly arranged and novelly constructed bellyrubbing plate. I I

Other objects will presently appear. Some of these will be obvious and others particularly noted.

A preferred embodiment of the invention is illustrated in the accompanying drawings, wherein:

Fig. 1,- a transverse section of the reservoirga-nd Fig. 5, a reduced top plan detail of the belly-plate. I I I 2 designates a board or other support which for the purposes of this specification may be termed a base. 3indicates a reservoir secured thereto by screw-bolts 4, having a depression or cupped bottom 5 (Fig. 5) extending from front to back and provided by curved side walls 5, and havingat eachinner corner and slightly below its upper edge a supporting lug 6 on which an inverted oil-can 7 rests, the can thus becoming the tank usually made as a part of the device. The can 7 shown is the ordinary one of'commerce, having a handle 8 and spout 9,.the latter extending to or slightly below the top of the walls 5. At the lower edge of the front wall of the reservoir is an opening 10 for the passage of oil there.- from. A valve-casing 11 is cast integral with the reservoir, as is also a spout 12 which communicates with the bore of said valve-casing by means ofian aperture 13 which lies in a higher horizontal plane than does the opening 10. 14, 1a designate forwardly projecting plate-guiding lugs also integral with the reservoir. 8 and provided with registering apertures for the reception of a plate-retaining bolt 15 which is engaged by a nut 16. i 17- designates a valve-stem or plunger provided at its upper end with ears 18 arranged diametrically opposite each other and having registeringeyes 19. The

stem 17 is provided with an axial recess 20 extending to near its lower end, where it communicates with smaller and larger transverse openings 21, 21 respectively, extending through the stem. The bore 20 of the stem is sufliciently deep to provide an oll-cup 20 which, together with the openings 21 and' 21 receive'a charge of oil at each downward movement (presently described)- of said stem, the opening 21 being normally closed by the wall of the valve-casing.

22 indicates a dirt-excluding plug. '23 designates an apertured lug or bracket on the bottom of the reservoir 3. g

Secured by bolts 24: and nuts 25 to the base 2 is a lower bracket26 having oppositely arranged arms 27 provided with registering apertures which receive a bolt 28 engagedby anut29- 30 designates a lug projecting between the arms 27 and 31 indicates a'web, both of which parts are integral with the casting 26. 32 indicates a plate connected by pins 32, 32"- with the lugs 2330 respectively and serving not only to prevent animals becoming fast between the base 2 and the rubbing-plate 33 presently described, but also as a brace or support for the reservoir andparts integral therewith.

33 indicates a channeled rubbing-plate having at its upper end a rearward extension or gooseneck 34 provided with an aperture which receives a bolt 35 which passes also through the apertures 19, in the valvestem ears. 36 indicates a nut on said bolt. At its lower end the plate 33 has oppositely disposed rearwardly extending projections 37 provided with registering slots 38. 39 indicates a roller-bearing mounted on the bolt .28 and inthe'slots 38. Near its upper end said plate is provided with an opening 55 toward which the spout 12 is directed, the lower'wallof said opening being provided by a shelf or ledge 4L0 onto which the oil drops from said spout. On its face said plate is provided with oppositely arranged obtuse angled embossments or spreaders 41 comprising each a vertically and a downwardly inclined branch, the inclination of the latter being in an alternate series, 'or each one inclined in a direction opposite to that of the adjacent one.

42 indicates a belly-rubbing plate secured by a pin l3 to the lug 31. The upper face ofits outer portion is channeled to receive and retain any oil which may drip from the plate 33.see Figs. 1 and 5. 44c designates one of a pair of braces (the other not shown) arranged on opposite sides of the plate 12 and connected thereto and to the base 3 by bolts 4546 respectively.

In order to hold the can securely but removably on the lugs 6 I provide an L-shaped bracket 4:? having a locking projection 48. The bracket 47 is pivotally secured to the base, as by a bolt 49 and wing-nut 50, where,

by when' it is' desired to' remove the can from the position shown it may be done by slightly loosening said nut and swinging the bracket toone side. To lock the can in place a reverse operation is performed.

In operation, the animal will rub against the plate 33 which will move freelyon its roller bearing 39, and the walls'of the inclined slots; 38'Iwill carry said plate and thereby the valve-stem upward. As hereina'bove stated, the openings 21,121 are filled with oil at each downward movement; of said stem. This small,-measured and inexpen sive quantity of oil will, when the, stem is raised as just describedf whereby theopening -21wcomes on a-level withthe opening 13-flow from the former into the latter, and thence down the spout12, from which it will droponto the shelf 40- and ,thencevflo'w down upon the plate. Inspection of Fig.3 willshow that when theopenings 13 .and 21 register, as just described,.the lower end of the plunger 17. has risen to a horizontalplane above the lower edge of the outlet 10 of the reservoir, thereby permitting the oil to flow into the bottom of the valve-casing. Then, upon the return or down stroke of the plunger it ,will completely .fillthe casing, thereby forcing back into the. reservoir that oil which had occupied the lower portion, of the casing. When medicatedor .mixedoils the constituents of which are of diiferent specific gravities are used, the force of the backward-rushing oil will stir up and thore oughly commingle said constituents and the supply will notbe drawn from the; heaviest alone thereof, as in the case of preceding devices of similar nature. Moreover, should .the' solid'ingredients of the oil collect'in the passage between the reservoir and valve-casing, the forcibly driven, backward moving oil will wash out and cle'ansefsaid passage. Inasmuch as the-plate 4:1,18' necessarily heavy, in order to withstand roughcontacts by the animals, its gravity will tend to jerk the plunger rapidly down, whereby to drive theoil back with like rapidity. :Shouldthe oil flow very, freely (because of the rapid and continued movements of the animal against the plate, andi:consequent rapid reciprocations of the valve-stem) .it willfiow from the terminal of each of the inclined branches of theembossments. 41 and strike thevertical branch of the one below, and so on in an evident manner; but if it comes slowly it will merely drip from one inclined branch onto the one below Should the animal bear against the vertically arranged plate in such manneras to cause thevalvestem to be held for a period of time inopen or oil-dischargingzposition, no oil otherthan that carriedin the valve-stem will be dis charged, for none can flow from the-reservoir thereinto until the valve-stem has dropped to its normal position. Any excess oil willdrip from the plate 83 into the cup 51 in the plate 42 and will be distributed over the bellies of the animals rubbing thereagainst. i 1

It has been thought neither necessary nor best toencumber this specification and the accompanying drawings with descriptions and illustrationsof modifications which are not essential to the invention, viewed in its broadest aspect. In fact, it willbe apparent without such that some of the features herein disclosed may be used without the others; that some may be embodied in de-' vices similar in nature but vastly different in structural characteristics; that some may be dispensed with; that the arrangement and disposition of some of the elements may be changed; and that many changes may be made in the details of construction. All of these changes I comprehend as residing within the scope of the invention. Therefore, without limiting myself to particularities, except where such are specifically pointed out, I claim as new the following, namely:

1. Combined in an animal oiler, a source of liquid-supply having an outlet immediately above its bottom, a valve-casing communicating therewith and having an outlet, the latter arranged in a higher horizontal plane than the former, a valve fitting snugly in the casing and having an axial opening extending from its top almost toits. bottom and adapted to contain a charge of liquid, and having also a transverse inlet and a transverse outlet, the former normally communicating with the source of liquid supply, the bottom of the valve adapted to rise above the first recited outlet, and means actuable by an animal whereby to cause said valve to rise and to discharge the liquid contained in its axial opening into the outlet in the Valve casing.

2. In combination, a valve casing having an inlet immediately above its bottom and having an outlet in a higher horizontal plane than the inlet, a supply-vessel communicating with said inlet, a valve having an axial opening extending from its top nearly to its bottom, having an inlet communicating with the inlet in the valve casing, and having an outlet, the liquid from the supply vessel adapted to pass into and fill the axial opening in the valve, and means for raising the valve to such position that its outlet will register with the outlet in the valve-casing and the liquid will flow from the axial opening in the valve out through the outlet in the casing.

33. In combination, a valve casing having an inlet immediately above its bottom and having an outlet in a higher horizontal plane than the inlet, a supply-vessel communicating with said inlet, a valve having an axial opening extending from its top nearly to its bottom, having an inlet communicating with the inlet inthe valve casing, and having an outlet, the liquid from the supply vessel adapted to pass into and fill the axial opening in the valve, a rubbing-plate for raising the valve to such position that its outlet will register with the outlet in the valve-casing and the liquid will flow from the axial opening in the valve out through the outlet in the casing and onto said plate, and a horizontally arranged rubbing'plate adapted to catch the drip from the first recited rubbing-plate.

4. In a device of the character described, a reservoir having an outlet, a valve casing communicating with said outlet, a hollow valve adapted to receive liquid from the first recited outlet and its lower end adapted to rise to a horizontal plane above the lower edge thereof, whereby to permit liquid to flow from the reservoir into the casing, and a movable element adapted in one of its movements to so move the valve that it will discharge the liquid from its hollow portion and in another of its movements drive back into the reservoir the liquid which entered the casing when the lower end of the valve rose above the lower edge of the reservoir outlet.
